Cleanser & Serum Two we keep rebuying. The cleanser is a near-perfect gentle pH 5.5 gel and it is unscented; the serum is excellent too, but it contains lavender oil, so read the label per product rather than trusting the brand.
★★★★★ 4.5/5 · Haruharu Wonder · Official list prices checked 2026-08-12: $17 for the 100 ml cleanser; $27–$32 for the 50 ml serum across official sites
Moisturiser At an example amount of 0.4 ml a day, current US prices work out to about $0.31 a day for 50 ml and $0.23 for 125 ml, but we have not measured actual use, so the family repeat purchase matters more than the estimate.
★★★★☆ 4.0/5 · Kiehl's · US list prices checked 2026-08-12: $39 for 1.7 oz / 50 ml; $72 for 4.2 oz / 125 ml
